LEBANON, N.H. — Authorities are investigating whether a New Hampshire man shot dead after a Vermont robbery may be connected to similar robberies in Lebanon.

Detectives with the Lebanon Police Department are investigating whether 51-year-old Larry Bohannon of Grafton could have been the man involved in the armed robberies at the Little Store and the Family Dollar store last month.

Bohannon was shot and killed by police Friday after allegedly robbing an office supplies store in Bellows Falls, Vt., at gunpoint and leading police on a chase that ended when the truck he was driving crashed in Walpole.
